在Allegro设计界面中如何修改封装焊盘

在Allegro PCB设计界面中修改封装焊盘的方法

1、选择菜单Tools→Padstack→Modify Design Padstack...

2、然后点击封装上要修改的焊盘，右击选择Edit

或者点击Options选项卡下要修改的焊盘，然后点击Edit修改

3、修改完焊盘后，选择File→Update to Design（更新到设计）。然后关闭焊盘修改对话框即可。

修改完成后如下图所示

4、另外在Parameters选项卡下，

在高密度板的情况下，SUIPLA（支持内层没有的焊盘摘掉）打勾，在高密度板的情况下，内层没有的焊盘摘掉可以增加走线的空间。

Allegro provides a good and interactive working interface and powerful functions, and its front-end products Cadence, OrCAD, Capture, the combination of high-speed, high-density, multi-layer complex PCB design routing provides the most perfect solution.

Allegro has perfect Constraint Settings, users only need to set the wiring rules according to the requirements, and the design requirements of the wiring can be achieved without violating the DRC when routing, thus saving the tedious manual inspection time and improving the work efficiency!

It can also define parameters such as minimum wire-width or wire-length to meet the needs of today's high-speed circuit board wiring.

Constraint Manger provides a simple interface for users to set and view Constraint declarations.

Its combination with Capture allows E.E. electronics engineers to set up regular data when drawing a circuit diagram and bring it with them to the Allegro working environment, where it can be automatically processed and checked when placing parts and wiring. The empirical values of these regular data can be reused for the same nature of the circuit board design.

In addition to the above functions, Allegro's powerful automatic push and stick line and perfect automatic repair line function provide users with great convenience;

The powerful mapping function can provide multiple users to deal with a complex board at the same time, thus greatly improving the work efficiency.

Or use the optional graph cutting function to cut the circuit board into various blocks, so that each block has a full-time person at the same time to design, to achieve the purpose of the same graph design and can shorten the time course.

After renaming, online interchange and modifying logic during routing, users can easily return to Capture wiring diagram, and update the wiring diagram to Allegro after modification.

Users can also click and modify objects between Capture and Allegro.文章来源地址https://www.toymoban.com/news/detail-420838.html
